chief,

Do you check Pajero Fieldmaster?

I am experiencing loss of power, black smoke on flooring or arangkada and high FC. Check / replace air filter before considering any repairs.

Do you also repair/check/parts for fieldmaster turbo?

Please advise.

thanks

[Dieseldude]

Hi Sir Diesel Dude thanks for the reply.

Nalimutan ko banggitin that the fuel filter has been replaced as well. Good.

The scan was made at our suking servitek and if i remeber correctly yung brand ng scanner nila was coincidentally innova din. Never heard of an Innova scan tool.

IACV and EGR are still in their original form. No repairs done yet. Did servitek assure you that fixing the IACV & EGR will correct the problem?

Still have to check the fuel supply pump and bleed the fuel lines. You can bleed the fuel supply lines to the pump. I don't suggest that you check the supply pump if you don't have the proper training and tools......... danger due to extremely high fuel pressures. Leave this to the experts.

There are days upon start up it will idle straight away but then there are also those when the symptoms re-appear. On normal driving everything seems to be ok no rough idling, no engine cutting out never pa naman tumirik or nag stop yung engine. This is a possible fuel supply pump problem.

Many thanks You're welcome.

sir jake,

need your help on this one.
what would be the problem of my nissan urvan homy subic td27 turbo a/t .i dont know kung trans problem ito.parang walang shifting from low gear to high gear. from stop and started at D gear ramdam ang shifting at 40kph speed up to 60kph.but from 60kph to 90kph onwards parang walang shifting coz rpm goes to 2500 up to 3000 hindi maramdaman ang shifting kahit galit na ang makina.atf was replaced recently,turbo was replaced also(old one was stuck up).injection pump was calibrated(mechanical).

TIA,

I'm not familiar with your ride but I would try this:

1. Check transmission oil filter
2. Check downshift cable adjustment
   
3. See if your injection pump has a throttle potentiometer mounted on top of the control shaft. This device is sometimes used to control transmission shift points.

I hope this helps. Good luck.........

thanks sir jake,
will try to check all the items stated.will keep you posted..

sir DD san po shop nyo, many thanks

Sir Diesel Dude,

My problem is engine knocking noise upon start up in the morning, but it disappears after about 30 seconds, okay la ba yun? kasi i had never heard it before siguro mga 3 days pa lang nagumpisa ang ingay. My ride is a 4x2 nissan frontier td27 engine

[ISO4113]

rasambo:

do you have any smoke when you start up in the morning? what color? white or black? naka on ba ang CHECK ENGINE light mo?

ano ang nangyare sa kotse before nag simula ito? nag over heat ba? nag change oil? more details give way to a better diagnosis.

regards,

Good morning sirs,



Can you recommend a good, reliable and affordable shop that can clean nozzles/check injection pumps? My hi-lander is nearing 180k kms, medyo mausok na rin even after it has warmed up. Ok naman power pero would like to have it checked just the same.


Thanks in advance!

First step: Check & replace Fuel Filter/Air cleaner. Replace if necessary, and see if emission improves.

180k kms is quite high....definitely, some wear on the engine and fuel system. "Just cleaning" is a misconception. When you bring your pump/injectors to a reputable shop, injectors are cleaned, tested for spray pattern, opening pressure, and backleakage. If failed, parts need to be replaced and calibrated to specs. etc...Pumps, cleaned, disassembled, parts inspected, replaced as needed, then mounted on test bench for calibration (bringing it back to original OE/like new condition)

Regarding smoke: White smoke would indicate a possible engine problem. Black smoke will most likely be related to your fuel systems (pump and Injectors), or air starvation.

Bear in mind that your vehicle has accumulated a lot of mileage.

thanks dieseldude! I regularly change my fuel and air filters eery 5k kms, but it still smokes. can you recommend me a good shop that can do all of these? mine has white smoke by the way.

Hi DieselDude,

tanong ko lang...nagtataka kasi ako kung bakit yung mga diesel engine dito sa atin eh parang ang bilis ata umusok lalo na yung Isuzu? Pero sa ibang countries naman eh hindi. I have a van kasi na galing japan and 260,xxx na yung ODO niya eh hindi naman mausok at wala naman prob sa engine...Ano ba ang mayron sa makina ng mga sasakyan sa ibang banda na wala yung makita dito sa atin?

[izzy06]

sir, bakit kaya hanggang 120km/hr lang ang top speed ng nissan frontier ko 2000 model 4x2 90km mileage, kahit off na ang a/c ko. para kasing pigil siya humatak pero tahimik naman at walang usok.

not seen any of the signs of trouble you mentioned above except dun sa pagstart ng sasakyan may lalabas na black smoke pero isang buga lang kasi raw diesel siya sir. Pero napacheck ko na most likely engine support raw sir

Oil change has no effect on smoke.

Does white smoke diminish as temperature increases?

If it does, you will most likely need an engine overhaul. But do a compression test just to make sure.

Baka barado ang fuel and/or air filter.

Or baka naman accelerator cable adjustment lang...... Pag sagad ng accelerator pedal, dapat sumagad rin ang injection pump lever sa maximum speed stopper bolt.

Kung hindi mag-improve, baka injection pump calibration ang kelangan.

Siguro dahil sa poor maintenance sa atin; baka dahil din sa kagipitan sa datong. Puro tayo remedyo at di nasusunod ang regular service schedules. Maayos siguro ang pagkaka-maintain ng ride mo kaya mahaba ang buhay.

Marami din diesel workshops dito na kulang sa training, technical information, at test equipment. Sa ibang bansa, umaandar ang batas lalo sa emission, malaki ang penalty at di malalagyan ang nanghuhuli. Dito, sa sobrang gustong makatipid, yan ang tawag na "napapamurang mahal". Pag di tama ang trabaho, umiiksi ang buhay ng makina natin.

[Dieseldude]

Pero napacheck ko na most likely engine support raw sir. Walang relasyon ang smoke sa engine support.......unless meron reklamong malakas na vibration.

Kung dating wala yan dapat mapa check mo. It can either be a fuel knock or an engine mechanical knock.

I have a 3. 0 fortuner with 60kms on it.* *Yesterday, it suddenly lost power.* As you step on the accelerator, the revs go up, but very slowly.* *No power at all until you reach 3,000rpm (which takes around ten seconds to do so) then the power kicks in.
*
Has anybody experienced this before?* I would appreciate any feedback/tips anyone might be able to provide.* *I do not know where to bring the car because i do not trust toyota casa.* * *

Before anything else, you should have your vehicle scanned for any faults logged in. I will pm you.

[torogi kid]

does it mean that my turbo is both Watercooled and Aircooled. may IN-OUT kasi yung water and oil paths sa Turbo...

and does it need a turbo timer?



thanks, may spare toyota 3c-tdi engine kasi kami, baka puwede ilagay sa aming 3c-td. hehe..

magtatanong lang po ako regarding turbo, yung kasing isuzu mu ng kapatid ko, may problema sa turbo. kung tumatakbo ito below 80kph, ok lang, di mausok. pag lagpas ng 80kph, yun yata ang time na mag kick in ang turbo, biglang bubulwak ang maitim na usok, parang nag le leak yung lubricant ng turbo sa exhaust manifold. kailangan mag slow down at maghintay ng mga 20 minutes bago mawala yung maitim na usok. pag chineck yung engine oil bawas na ito. ang tanong ko ay, pwede ba idisable yung turbo, para maging naturally aspirated ang engine? malaking trabaho ba ang pag convert nito? may effect ba sya sa engine performance? habang nag iipon nang pang repair, ano ang pwede gawin pansamantala para lang mawala yung maitim na usok, habang nasa 80+ ang speed? please help!!
